No common English word rhymes with 'laxative' (/ˈlæksətɪv/). Words like 'sedative' (/ˈsɛdətɪv/), 'relative' (/ˈrɛlətɪv/) and 'negative' (/ˈnɛɡətɪv/) share the written suffix '-ative' and the unstressed ending /ətɪv/, but their stressed vowels differ, so they do not rhyme. Beware of lookalikes: 'lactic' (/ˈlæktɪk/) is spelled similarly but has no /s/ or /tɪv/ ending, while 'lax' (/læks/) and 'laxity' (/ˈlæksɪti/) share the /læk(s)/ sound with the first syllable.
